🚨 MAJOR SECURITY UPGRADE: W3C Verifiable Credentials v2.0 Just Dropped These Game-Changing Security Features!

• Enhanced Device Security: Added password, biometric, or multi-factor authentication requirements for credential repositories to prevent device theft and impersonation attacks
• Improved Security Terminology: Updated language to use proper technical terms like 'credential repository' instead of generic terms
• Strengthened Security Documentation: Added comprehensive security considerations covering cryptography suites, key management, and content integrity protection
• Enhanced Attack Prevention: Detailed guidance on preventing man-in-the-middle attacks, replay attacks, and spoofing attacks
• Better Security Practices: Added requirements for non-repudiation mechanisms and proof of control for verifiable presentations

The W3C Verifiable Credentials Data Model v2.0 is a comprehensive standard for creating secure, tamper-evident digital credentials that enable trusted data exchange between issuers, holders, and verifiers. This specification provides a robust framework for expressing claims about subjects (like people, organizations, or things) in a way that's cryptographically secure, privacy-respecting, and machine-verifiable. The standard supports various credential types from driver's licenses to educational certificates, enabling selective disclosure of information while maintaining trust through digital signatures and zero-knowledge proofs. The ecosystem operates through three key roles: issuers who create credentials, holders who store and present them, and verifiers who check their authenticity.
